[Tom Goddard]

The user opened a command script and in nucleotides make_molecule() it tried to update the ribbon graphics and failed with an error message that doesn't make sense about XSectionManager not being subscriptable where the line does not appear to be doing any subscripting.

File "C:\Program Files\ChimeraX 1.11.1\bin\Lib\site-
packages\chimerax\atomic\ribbon.py", line 2070, in xs_coil  
if self._xs_coil is None:  
^^^^^^^^^^^^^  
TypeError: 'XSectionManager' object is not subscriptable  

In subsequent errors (likely caused by this first error) it is in the xs_coil property of XSectionManager and executing self._make_xs() and says RibbonXSection has no method _make_xs. Here self should be an XSectionManager but apparently it is instead a RibbonXSection.
